UNIFORM TEXTURE FOR CAST IN PLACE WALLS
A method of forming a concrete wall having a substantially uniform exterior surface texture. The method includes the initial step of pouring concrete into a wall form. The concrete is poured from a first mixture and is allowed to cure. After the concrete is cured, the wall form is removed from the resultant concrete base structure. A roughened texture is then created on the base structure. A finishing mixture is then applied to the roughened texture. The finishing mixture may be created by separating the aggregate from a portion of the remaining first mixture. The finishing mixture creates a smooth texture on the exterior surfaces of the initially formed base structure.
1 . A method of forming a concrete structure comprising the steps of:
(a) pouring a first concrete mixture into a wall form, wherein the first concrete mixture includes large aggregate;
(b) curing the first concrete mixture to form a concrete base structure;
(c) removing the wall form from the base structure;
(d) creating a roughened exterior surface on the base structure;
(e) creating a finishing mixture by separating the large aggregate from a portion of the first concrete mixture; and
(f) applying the finishing mixture to the roughened exterior surface of the base structure.
2 . The method of claim 1 , wherein the roughened exterior surface is created by applying a form retarder to the base structure.
3 . The method of claim 1 , wherein the roughened exterior surface is created by applying a spray on retarder to the base structure.
4 . The method of claim 1 , wherein the roughened surface is created by sand blasting the base structure.
5 . The method of claim 1 , wherein the roughened surface is created by acid washing the base structure.
6 . The method of claim 1 , wherein the roughened surface is created by chemically etching the base structure.
7 . The method of claim 1 , further comprising the step of troweling the finishing mixture once applied to the base structure.
8 . The method of claim 1 , further comprising the step of allowing the finishing mixture to cure.
9 . The method of claim 8 , further comprising the step of acid washing the cured finishing mixture.
10 . A method of forming a concrete structure comprising the steps of:
(a) pouring a first concrete mixture into a wall form, wherein the first concrete mixture contains large aggregate;
(b) curing the first concrete mixture to form a concrete base structure;
(c) removing the wall form from the base structure;
(d) creating a roughened surface on the base structure;
(e) creating a finishing mixture by separating large aggregate from a second mixture of concrete; and
(f) applying the finishing mixture to the roughened exterior surface of the base structure.
11 . The method of claim 10 , wherein the roughened exterior surface is created by applying a form retarder to the base structure.
12 . The method of claim 10 , wherein the roughened exterior surface is created by applying a spray on retarder to the base structure.
13 . The method of claim 10 , wherein the roughened surface is created by sand blasting the base structure.
14 . The method of claim 10 , wherein the roughened surface is created by acid washing the base structure.
15 . The method of claim 10 , wherein the roughened surface is created by chemically etching the base structure.
16 . The method of claim 10 , further comprising the step of allowing the finishing mixture to cure.
17 . The method of claim 16 , further comprising the step of acid washing the finishing mixture.
18 . A method of forming a concrete structure having a substantially uniform exterior surface texture, comprising the steps of:
(a) curing a first mixture of concrete including large aggregate to form a concrete base structure;
(b) creating a finishing mixture by separating the large aggregate from a portion of the first concrete mixture; and
(c) applying the finishing mixture to the base structure.
19 . The method of claim 18 wherein step (a) comprises initially pouring the first mixture of concrete into a wall form.
20 . The method of claim 18 wherein step (a) further comprises creating a roughened exterior surface on the base structure.
